The Bosch EXPERT 5 Piece HEX-9 Multi Construction Drill Bit Set is a premium multi-material drill bit set designed for tradespeople who need to move confidently between substrates on site. Engineered for precision across a wide range of materials — including granite, concrete, brick, soft tile, wood, and metal — these bits are up to 5x more precise than the Bosch CYL-3. The advanced Bosch Centering Geometry ensures a slip-free start on even the hardest surfaces, eliminating skidding and delivering a stabilised drilling action from the first contact. Each bit features a high-performance carbide tip manufactured using a fine grinding technique, allowing razor-sharp cutting edges that maintain efficiency across hundreds of clean holes. The optimised dust extraction channel works in conjunction with the fluting to clear chips rapidly, keeping the drilling process fast and the finish professional. The HEX-9 hex shank provides a secure, high-torque connection compatible with both three-jaw chucks and ¼" internal hex tool holders, making these bits suitable for a wide range of cordless drills and drivers. Ideal for contractors, builders, and multi-trade professionals working across varied materials without the time to swap bit sets.
